Abstract

An automatically generating program and device are provided which can easily and accurately create an operation program with no need of providing an image data input device. The program, causes a work head to move relative to a work object and to carry out desired work, includes the steps of displaying a reference data input window which allows input of shape data of the work object or a work region (STEP 201 ), taking in image data of the work object or the work region (STEP 202 ), compensating for distortion in the taken-in image data (STEP 203 ), displaying a movement path input window which allows designation of a movement path with the compensated image data displayed as a background (STEP 204 ), and automatically generating the operation program based on the movement path that is designated on the movement path input window (STEP 205 ).

First claim

The invention claimed is:

1. A non-transitory a computer-readable storage medium comprising instructions stored thereon for automatically generating an operation program, which causes a work head to move relative to a work object and to carry out desired work, that when executed on a processor, perform the steps of:
a first step of displaying a reference data input window which allows input of shape data of the work object or a work region on a display device;
a second step of taking in image data of the work object or the work region, the image data being captured by an image data input device;
a third step of compensating for distortion in the image data taken-in from the image data input device, the distortion attributable to arrangement of the image data input device, based on the input shape data of the work object or the work region;
a fourth step of displaying a movement path input window which allows designation of a movement path with the compensated image data displayed as a background; and
a fifth step of automatically generating the operation program based on the movement path that is designated on the movement path input window,
wherein, in the third step, a shape reference line, having a shape substantially the same as the shape of the work object or the work region, is prepared and displayed on the display device together with the work object or the work region, distortion in the image data attributable to arrangement of the image data input device is compensated for based on the input shape data by deforming the shape reference line to conform with an external shape of the work object or the work region on the display device.

2. The non-transitory computer-readable medium according to claim 1 , wherein, in the first step, the reference data input window allows input of reference coordinates of the work head.

3. An operation program creating device comprising non-transitory computer-readable medium according to claim 2 , an input device, a display device, and a processor.

4. The non-transitory computer-readable medium according to claim 1 , wherein the work object or the work region has a square shape, and the shape reference line has a square shape.

5. The non-transitory computer-readable medium according to claim 4 , wherein, in the third step, corners of the work object or the work region are automatically detected, and the corners of the work object or the work region are automatically aligned with corresponding corners of the shape reference line in superimposed relation.

6. The non-transitory computer-readable medium according to claim 5 , wherein, in the third step, the distortion in the image data attributable to the arrangement of the image data input device is compensated for by rearranging individual pixels in the work object or the work region, which is designated by the shape reference line, through coordinate transform using a geometrical transform technique such that the shape reference line has a square shape in conformity with the input shape data.

7. The non-transitory computer-readable medium according to claim 4 , wherein, in the third step, the distortion in the image data attributable to the arrangement of the image data input device is compensated for by rearranging individual pixels in the work object or the work region, which is designated by the shape reference line, through coordinate transform using a geometrical transform technique such that the shape reference line has a square shape in conformity with the input shape data.

8. The non-transitory computer-readable medium according to claim 1 , wherein, in the fourth step, the designated movement path is displayed in real time on the window in accordance with a preset width value.

9. The non-transitory computer-readable medium according to claim 1 , wherein, in the fourth step, when an anomalous point is present in the designated movement path, the movement path is displayed in real time on the window with the anomalous point displayed in a different color.

10. The non-transitory computer-readable medium according to claim 1 , further comprising a step of taking in image data of a substrate for calibration, and compensating for aberrations of a lens based on input calibration values.

11. An operation program creating device comprising non-transitory computer-readable medium according to claim 1 , an input device, a display device, and a processor.

12. The non-transitory computer-readable storage medium according to claim 1 , wherein the work object is a substrate.

13. A working apparatus comprising a work head, a holder for holding a work object, a driver to move the work head and the holder relative to each other, a reading device, a display device, an input device, and a control unit, the working apparatus carrying out desired work while the work head is moved relative to the work object based on image data of the work object or a work region, the image data being taken in from the reading device,
wherein the image data of the work object or the work region is obtained by capturing image data of the work object or the work region with an image data input device, and
the control unit is configured to execute:
a step of compensating for distortion in the image data of the work object or the work region data based on the input shape data of the work object or the work region, the distortion including an inclination of an image attributable to arrangement of the image data input device and the image data being taken in from the reading device, based on shape data of the work object or the work region, the shape data being input through the input device,
a step of displaying, on the display device, a movement path input window which allows designation of a movement path with respect to the compensated image data displayed as a background, and
a step of automatically generating an operation program based on the movement path that is designated on the movement path input window,

wherein, in the step of compensating, a shape reference line having a shape substantially the same as a shape of the work object or the work region, is prepared and displayed on the display device together with the work object or the work region, distortion in the image data attributable to arrangement of the image data input device is compensated for based on the input shape data by deforming the shape reference line to conform with an external shape of the work object or the work region on the display device.

14. The working apparatus according to claim 13 , wherein the control unit automatically creates the operation program based on reference coordinates of the work head, the reference coordinates being input through the input device.
